Panchakarma ("Pancha" means five and "karma" means treatment) is performed to detoxify the body according to Ayurveda. The five procedures are claimed to eliminate the vitiated Doshas from the body. They are Vamana (emesis), Virechana (purgation), Niroohavasti (decoction enema), Nasya (Instillation of medicine through nostrils), and Anuvasanavasti (oil enema). Nirooha, Anuvasana and Uttaravasthi form the basic types of Vasti. The term Panchasodhana includes Vamana, Virechana, Nasya, Nirooha, and Rakthamoksha (Blood letting).
